Struct SegmentView 

pub struct SegmentView<'provider> {
    pub structure: Arc<ParsedSegment>,
    pub bytes: SegmentBytes<'provider>,
}

One segment’s parsed structure together with its raw bytes.

Fields

structure: Arc<ParsedSegment>

The parsed header and tables.

bytes: SegmentBytes<'provider>

The segment’s stored bytes.

Implementations

impl SegmentView<'_>

pub fn record_position(&self, record_number: u32) -> Result<usize>

Resolves a record number to a position in Self::bytes.

pub fn read_bytes( &self, record_number: u32, offset: usize, length: usize, ) -> Result<&[u8]>

Reads length bytes starting offset bytes into the record.

pub fn read_u8(&self, record_number: u32, offset: usize) -> Result<u8>

Reads one byte of the record.

pub fn read_u16(&self, record_number: u32, offset: usize) -> Result<u16>

Reads a big-endian unsigned 16-bit integer.

pub fn read_u32(&self, record_number: u32, offset: usize) -> Result<u32>

Reads a big-endian unsigned 32-bit integer.

pub fn read_u64(&self, record_number: u32, offset: usize) -> Result<u64>

Reads a big-endian unsigned 64-bit integer.

pub fn read_record_identifier( &self, record_number: u32, raw_offset: usize, identifier_index: usize, ) -> Result<RecordIdentifier>

Reads the serialized record identifier stored at raw_offset + identifier_index * 6 bytes into the record: a 16-bit segment reference (0 means this segment, n > 0 means entry n - 1 of the segment reference table) followed by a 32-bit record number.
